"Shhhhh..." Erwin definitely heard Levi suck in his breath, and how he's starting to ramble. He runs his hand up Levi's back, along his spine, and presses it between his shoulders, drawing Levi in against him while also, hopefully, easing some of the tension that he's almost certain has started building during this conversation. He trails his lips down the column of Levi's throat to his collarbone, and gently nudges Levi's shirt out of the way.

"I have so many things I can show you." Erwin lifts his gaze then, meets Levi's eyes, and smiles. "I'm going to teach you everything I know."

Okay, his bag of tricks really isn't that big--he's not Gunther, that man had banged his way across half the walls and had the raunchiest stories in the Corps, of which Levi has no doubt heard many--but he's starting ahead of square one, which means he'll be in the lead here. For whatever reason, that idea makes him even more excited, and Erwin pointedly presses his erection against Levi's thigh.

"We're going to have so much fun."
